BACKGROUND

1. Field of Invention

The present invention relates generally to compositions comprising1-chloro-3,3,3-trifluoropropene. More specifically, the presentinvention provides azeotrope-like compositions comprising1-chloro-3,3,3-trifluoropropene and uses thereof.

2. Description of Related Art

Fluorocarbon based fluids, including chlorofluorocarbons (“CFCs”) orhydrochlorofluorocarbons (“HCFCs”), have properties that are desirablein industrial refrigerants, blowing agents, heat transfer media,solvents, gaseous dielectrics, and other applications. For theseapplications, the use of single component fluids or azeotrope-likemixtures, i.e., those which do not substantially fractionate on boilingand evaporation, are particularly desirable.

Unfortunately, suspected environmental problems, such as global warmingand ozone depletion, have been attributed to the use of some of thesefluids, thereby limiting their contemporary use. Hydrofluoroolefins(“HFOs”) have been proposed as possible replacements for such CFCs,HCFCs, and HFCs. However, the identification of new,environmentally-safe, non-fractionating mixtures comprising HFOs arecomplicated due to the fact that azeotrope formation is not readilypredictable. Therefore, industry is continually seeking new HFO-basedmixtures that are acceptable and environmentally safer substitutes forCFCs, HCFCs, and HFCs. This invention satisfies these needs amongothers.

DESCRIPTION OF PREFERRED EMBODIMENTS

According to certain embodiments, the present invention providesazeotrope-like compositions comprising, and preferably consistingessentially of, HFO-1233zd and a C₁-C₃ alcohol, a C₅-C₆ hydrocarbon,cyclopentene, a halogenated hydrocarbon selected from 1-chloropropane,2-chloropropane, and 1,1,1,3,3-pentafluorobutane, nitromethane, orwater. Thus, the present invention overcomes the aforementionedshortcomings by providing azeotrope-like compositions that are, inpreferred embodiments, substantially free of CFCs, HCFCs, and HFCs andhave very low global warming potentials have low ozone depletionpotential, and which exhibit relatively constant boiling pointcharacteristics.

As used herein, the term “azeotrope-like” relates to compositions thatare strictly azeotropic or that generally behave like azeotropicmixtures. An azeotropic mixture is a system of two or more components inwhich the liquid composition and vapor composition are equal at thestated pressure and temperature. In practice, this means that thecomponents of an azeotropic mixture are constant-boiling or essentiallyconstant-boiling and generally cannot be thermodynamically separatedduring a phase change. The vapor composition formed by boiling orevaporation of an azeotropic mixture is identical, or substantiallyidentical, to the original liquid composition. Thus, the concentrationof components in the liquid and vapor phases of azeotrope-likecompositions change only minimally, if at all, as the composition boilsor otherwise evaporates. In contrast, boiling or evaporatingnon-azeotropic mixtures changes the component concentrations in theliquid phase to a significant degree.

As used herein, the term “consisting essentially of”, with respect tothe components of an azeotrope-like composition, means the compositioncontains the indicated components in an azeotrope-like ratio, and maycontain additional components provided that the additional components donot form new azeotrope-like systems. For example, azeotrope-likemixtures consisting essentially of two compounds are those that formbinary azeotropes, which optionally may include one or more additionalcomponents, provided that the additional components do not render themixture non-azeotropic and do not form an azeotrope with either or bothof the compounds.

The term “effective amounts” as used herein refers to the amount of eachcomponent which, upon combination with the other component, results inthe formation of an azeotrope-like composition of the present invention.

Unless otherwise specified, the term HFO-1233zd means the cis-isomer,the trans-isomer, or some mixture thereof.

As used herein, the term cis-HFO-1233zd with respect to a component ofan azeotrope-like mixture, means the amount cis-HFO-1233zd relative toall isomers of HFO-1233zd in azeotrope-like compositions is at leastabout 95%, more preferably at least about 98%, even more preferably atleast about 99%, even more preferably at least about 99.9%. In certainpreferred embodiments, the cis-HFO-1233zd component in azeotrope-likecompositions of the present invention is essentially purecis-HFO-1233zd.

As used herein, the term trans-HFO-1233zd with respect to a component ofan azeotrope-like mixture, means the amount trans-HFO-1233zd relative toall isomers of HFO-1233zd in azeotrope-like compositions is at leastabout 95%, more preferably at least about 98%, even more preferably atleast about 99%, even more preferably at least about 99.9%. In certainpreferred embodiments, the trans-HFO-1233zd component in azeotrope-likecompositions of the present invention is essentially puretrans-HFO-1233zd.

As used herein, the term “ambient pressure” with respect to boilingpoint data means the atmospheric pressure surrounding the relevantmedium. In general, ambient pressure is 14.7 psia, but could vary +/−0.5psi.

The azeotrope-like compositions of the present invention can be producedby combining effective amounts of HFO-1233zd with one or more othercomponents, preferably in fluid form. Any of a wide variety of methodsknown in the art for combining two or more components to form acomposition can be adapted for use in the present methods. For example,HFO-1233zd and methanol can be mixed, blended, or otherwise combined byhand and/or by machine, as part of a batch or continuous reaction and/orprocess, or via combinations of two or more such steps. In light of thedisclosure herein, those of skill in the art will be readily able toprepare azeotrope-like compositions according to the present inventionwithout undue experimentation.

Fluoropropenes, such as CF₃CCl═CH₂, can be produced by known methodssuch as catalytic vapor phase fluorination of various saturated andunsaturated halogen-containing C3 compounds, including the methoddescribed in U.S. Pat. Nos. 2,889,379; 4,798,818 and 4,465,786, each ofwhich is incorporated herein by reference.

EP 974,571, also incorporated herein by reference, discloses thepreparation of 1,1,1,3-chlorotrifluoropropene by contacting1,1,1,3,3-pentafluoropropane (HFC-245fa) in the vapor phase with achromium based catalyst at elevated temperature, or in the liquid phasewith an alcoholic solution of KOH, NaOH, Ca(OH)₂ or Mg(OH)₂. The endproduct is approximately 90% by weight of the trans isomer and 10% byweight cis. Preferably, the cis isomers are substantially separated fromthe trans forms so that the resultant preferred form of1-chloro-3,3,3-trifluoropropene is more enriched in the cis isomer.Because the cis isomer has a boiling point of about 40° C. in contrastwith the trans isomer boiling point of about 20° C., the two can easilybe separated by any number of distillation methods known in the art.However, a preferred method is batch distillation. According to thismethod, a mixture of cis and trans 1-chloro-3,3,3-trifluoropropene ischarged to the reboiler. The trans isomer is removed in the overheadleaving the cis isomer in the reboiler. The distillation can also be runin a continuous distillation where the trans isomer is removed in theoverhead and the cis isomer is removed in the bottom. This distillationprocess can yield about 99.9+% puretrans-1-chloro-3,3,3-trifluoropropene and 99.9+%cis-1-chloro-3,3,3-trifluoropropene.

Blowing Agents:

In another embodiment of the invention, provided are blowing agentscomprising at least one azeotrope-like mixture described herein. Polymerfoams are generally of two general classes: thermoplastic foams andthermoset foams.

Thermoplastic foams are produced generally via any method known in theart, including those described in Throne, Thermoplastic Foams, 1996,Sherwood Publishers, Hinkley, Ohio, or Klempner and Sendijarevic,Polymeric Foams and Foam Technology, 2^(nd) Edition 2004, Hander GardnerPublications. Inc, Cincinnati, Ohio. For example, extruded thermoplasticfoams can be prepared by an extrusion process whereby a solution ofblowing agent in molten polymer, formed in an extruder under pressure,is forced through an orifice onto a moving belt at ambient temperatureor pressure or optionally at reduced pressure to aid in foam expansion.The blowing agent vaporizes and causes the polymer to expand. Thepolymer simultaneously expands and cools under conditions that give itenough strength to maintain dimensional stability at the timecorresponding to maximum expansion. Polymers used for the production ofextruded thermoplastic foams include, but are not limited to,polystyrene, polyethylene (HDPE, LDPE, and LLDPE), polypropylene,polyethylene terephthalate, ethylene vinyl acetate, and mixturesthereof. A number of additives are optionally added to the moltenpolymer solution to optimize foam processing and properties including,but not limited to, nucleating agents (e.g., talc), flame retardants,colorants, processing aids (e.g., waxes), cross linking agents,permeability modifiers, and the like. Additional processing steps suchas irradiation to increase cross linking, lamination of a surface filmto improve foam skin quality, trimming and planning to achieve foamdimension requirements, and other processes may also be included in themanufacturing process.

In general, the blowing agent may include the azeotrope-likecompositions of the present invention in widely ranging amounts. It isgenerally preferred, however, that the blowing agents comprise at leastabout 15% by weight of the blowing agent. In certain preferredembodiments, the blowing agent comprises at least about 50% by weight ofthe present compositions, and in certain embodiments the blowing agentconsists essentially of the present azeotrope-like composition. Incertain preferred embodiments, the blowing agent includes, in additionto the present azeotrope-like mixtures, one or more co-blowing agents,fillers, vapor pressure modifiers, flame suppressants, stabilizers, andlike adjuvants.

In certain preferred embodiments, the blowing agent is characterized asa physical (i.e., volatile) blowing agent comprising the azeotrope-likemixture of the present invention. In general, the amount of blowingagent present in the blended mixture is dictated by the desired foamdensities of the final foams products and by the pressure and solubilitylimits of the process. For example, the proportions of blowing agent inparts by weight can fall within the range of about 1 to about 45 parts,more preferably from about 4 to about 30 parts, of blowing agent per 100parts by weight of polymer. The blowing agent may comprise additionalcomponents mixed with the azeotrope-like composition, includingchlorofluorocarbons such as trichlorofluoromethane (CFC-11),dichlorodifluoromethane (CFC-12), hydrochlorofluorocarbons such as1,1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane(HCFC-142b), chlorodifluoromethane (HCFC-22), hydrofluorocarbons such as1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a),1,1,1,3,3-pentafluoropropane (HFC-245fa), and1,1,1,3,3-pentafluorobutane (HFC-365mfc), hydrocarbons such as propane,butane, isobutane, cyclopentane, carbon dioxide, chlorinatedhydrocarbons alcohols, ethers, ketones and mixtures thereof.

In certain embodiments, the blowing agent is characterized as a chemicalblowing agent. Chemical blowing agents are materials that, when exposedto temperature and pressure conditions in the extruder, decompose toliberate a gas, generally carbon dioxide, carbon monoxide, nitrogen,hydrogen, ammonia, nitrous oxide, of mixtures thereof. The amount ofchemical blowing agent present is dependent on the desired final foamdensity. The proportions in parts by weight of the total chemicalblowing agent blend can fall within the range of from less than 1 toabout 15 parts, preferably from about 1 to about 10 parts, of blowingagent per 100 parts by weight of polymer.

In certain preferred embodiments, dispersing agents, cell stabilizers,surfactants and other additives may also be incorporated into theblowing agent compositions of the present invention. Surfactants areoptional, but preferably are added to serve as cell stabilizers. Somerepresentative materials are sold under the names of DC-193, B-8404, andL-5340 which are, generally, polysiloxane polyoxyalkylene blockco-polymers such as those disclosed in U.S. Pat. Nos. 2,834,748,2,917,480, and 2,846,458, each of which are incorporated herein byreference. Other optional additives for the blowing agent mixtureinclude flame retardants or suppressants such astri(2-chloroethyl)phosphate, tri(2-chloropropyl)phosphate,tri(2,3-dibromopropyl)-phosphate, tri(1,3-dichloropropyl)phosphate,diammonium phosphate, various halogenated aromatic compounds, antimonyoxide, aluminum trihydrate, polyvinyl chloride, and the like. Withrespect to thermoset foams, in general any thermoset polymer can beused, including but not limited to polyurethane, polyisocyanurate,phenolic, epoxy, and combinations thereof. In general these foams areproduced by bringing together chemically reactive components in thepresence of one or more blowing agents, including the azeotrope-likecomposition of this invention and optionally other additives, includingbut not limited to cell stabilizers, solubility enhancers, catalysts,flame retardants, auxiliary blowing agents, inert fillers, dyes, and thelike. With respect to the preparation of polyurethane orpolyisocyanurate foams using the azeotrope like compositions describedin the invention, any of the methods well known in the art can beemployed, see Saunders and Frisch, Volumes I and II PolyurethanesChemistry and Technology (1962) John Wiley and Sons, New York, N.Y. Ingeneral, polyurethane or polyisocyanurate foams are prepared bycombining an isocyanate, a polyol or mixture of polyols, a blowing agentor mixture of blowing agents, and other materials such as catalysts,surfactants, and optionally, flame retardants, colorants, or otheradditives.

It is convenient in many applications to provide the components forpolyurethane or polyisocyanurate foams in preblended formulations. Mosttypically, the foam formulation is preblended into two components. Theisocyanate and optionally certain surfactants and blowing agentscomprise the first component, commonly referred to as the “A” component.The polyol or polyol mixture, surfactant, catalysts, blowing agents,flame retardant, and other isocyanate reactive components comprise thesecond component, commonly referred to as the “B” component.Accordingly, polyurethane or polyisocyanurate foams are readily preparedby bringing together the A and B side components either by hand mix forsmall preparations and, preferably, machine mix techniques to formblocks, slabs, laminates, pour-in-place panels and other items, sprayapplied foams, froths, and the like. Optionally, other ingredients suchas fire retardants, colorants, auxiliary blowing agents, water, and evenother polyols can be added as a third stream to the mix head or reactionsite. Most conveniently, however, they are all incorporated into one BComponent as described above.

Any organic polyisocyanate can be employed in polyurethane orpolyisocyanurate foam synthesis inclusive of aliphatic and aromaticpolyisocyanates. Preferred as a class are the aromatic polyisocyanates.Typical aliphatic polyisocyanates are alkylene diisocyanates such astri, tetra, and hexamethylene diisocyanate, isophorene diisocyanate,4,4′-methylenebis(cyclohexyl isocyanate), and the like; typical aromaticpolyisocyanates include m-, and p-phenylene diisocyanate, polymethylenepolyphenyl isocyanate, 2,4- and 2,6-toluenediisocyanate, dianisidinediisocyanate, bitoylene isocyanate, naphthylene 1,4-diisocyanate,bis(4-isocyanatophenyl)methene, bis(2-methyl-4-isocyanatophenyl)methane,and the like.

Preferred polyisocyanates are the polymethylene polyphenyl isocyanates,particularly the mixtures containing from about 30 to about 85 percentby weight of methylenebis(phenyl isocyanate) with the remainder of themixture comprising the polymethylene polyphenyl polyisocyanates offunctionality higher than 2.

Typical polyols used in the manufacture of polyurethane foams include,but are not limited to, aromatic amino-based polyether polyols such asthose based on mixtures of 2,4- and 2,6-toluenediamine condensed withethylene oxide and/or propylene oxide. These polyols find utility inpour-in-place molded foams. Another example is aromatic alkylamino-basedpolyether polyols such as those based on ethoxylated and/or propoxylatedaminoethylated nonylphenol derivatives. These polyols generally findutility in spray applied polyurethane foams. Another example issucrose-based polyols such as those based on sucrose derivatives and/ormixtures of sucrose and glycerine derivatives condensed with ethyleneoxide and/or propylene oxide.

Examples of polyols used in polyurethane modified polyisocyanurate foamsinclude, but are not limited to, aromatic polyester polyols such asthose based on complex mixtures of phthalate-type or terephthalate-typeesters formed from polyols such as ethylene glycol, diethylene glycol,or propylene glycol. These polyols are used in rigid laminatedboardstock, can be blended with other types of polyols such as sucrosebased polyols, and used in other polyurethane foam applications such asdescribed above.

Catalysts used in the manufacture of polyurethane foams are typicallytertiary amines including, but not limited to, N-alkylmorpholines,N-alkylalkanolamines, N,N-dialkylcyclohexylamines, and alkylamines wherethe alkyl groups are methyl, ethyl, propyl, butyl, and the like andisomeric forms thereof; and hetrocyclic amines. Typical, but notlimiting examples are triethylenediamine, tetramethylethylenediamine,bis(2-dimethylaminoethyl)ether, triethylamine, tripropylamine,tributylamine, triamylamine, pyridine, quinoline, dimethylpiperazine,piperazine, N,N-dimethylcyclohexylamine, N-ethylmorpholine,2-methylpiperazine, N,N-dimethylethanolamine, tetramethylpropanediamine,methyltriethylenediamine, and the like, and mixtures thereof.

Optionally, non-amine polyurethane catalysts are used. Typical of suchcatalysts are organometallic compounds of bismuth, lead, tin, titanium,antimony, uranium, cadmium, cobalt, thorium, aluminum, mercury, zinc,nickel, cerium, molybdenum, vanadium, copper, manganese, zirconium, andthe like. Included as illustrative are bismuth nitrate, lead2-ethylhexoate, lead benzoate, ferric chloride, antimony trichloride andantimony glycolate. A preferred organo-tin class includes the stannoussalts of carboxylic acids such as stannous octoate, stannous2-ethylhexoate, stannous laurate, and the like, as well as dialkyl tinsalts of carboxylic acids such as dibutyl tin diacetate, dibutyl tindilaurate, dioctyl tin diacetate, and the like.

In the preparation of polyisocyanurate foams, trimerization catalystsare used for the purpose of converting the blends in conjunction withexcess A component to polyisocyanurate-polyurethane foams. Thetrimerization catalysts employed can be any catalyst known to oneskilled in the art, including, but not limited to, glycine salts andtertiary amine trimerization catalysts and alkali metal carboxylic acidsalts and mixtures of the various types of catalysts. Preferred specieswithin the classes are potassium acetate, potassium octoate, andN-(2-hydroxy-5-nonylphenol)methyl-N-methylglycinate.

Dispersing agents, cell stabilizers, and surfactants can be incorporatedinto the present blends. Surfactants, which are, generally, polysiloxanepolyoxyalkylene block co-polymers, such as those disclosed in U.S. Pat.Nos. 2,834,748, 2,917,480, and 2,846,458, which are incorporated hereinby reference.

Other optional additives for the blends can include flame retardantssuch as tris(2-chloroethyl)phosphate, tris(2-chloropropyl)phosphate,tris(2,3-dibromopropyl)phosphate, tris(1,3-dichloropropyl)phosphate,diammonium phosphate, various halogenated aromatic compounds, antimonyoxide, aluminum trihydrate, polyvinyl chloride, and the like. Otheroptional ingredients can include from 0 to about 3 percent water, whichchemically reacts with the isocyanate to produce carbon dioxide. Thiscarbon dioxide acts as an auxiliary blowing agent.

Also included in the mixture are blowing agents or blowing agent blendsas disclosed in this invention. Generally speaking, the amount ofblowing agent present in the blended mixture is dictated by the desiredfoam densities of the final polyurethane or polyisocyanurate foamsproduct. The proportions in parts by weight of the total blowing agentblend can fall within the range of from 1 to about 45 parts of blowingagent per 100 parts of polyol, preferably from about 4 to about 30parts.

The polyurethane foams produced can vary in density from about 0.5 poundper cubic foot to about 40 pounds per cubic foot, preferably from about1.0 to 20.0 pounds per cubic foot, and most preferably from about 1.5 to6.0 pounds per cubic foot. The density obtained is a function of howmuch of the blowing agent or blowing agent mixture disclosed in thisinvention is present in the A and/or B components, or alternativelyadded at the time the foam is prepared.

Foams and Foamable Compositions:

Certain embodiments of the present invention involve a foam comprising apolyurethane-, polyisocyanurate-, or phenolic-based cell wall and a cellgas disposed within at least a portion of the cells, wherein the cellgas comprises the azeotrope-like mixture described herein. In certainembodiments, the foams are extruded thermoplastic foams. Preferred foamshave a density ranging from about 0.5 pounds per cubic foot to about 60pounds per cubic foot, preferably from about 1.0 to 20.0 pounds percubic foot, and most preferably from about 1.5 to 6.0 pounds per cubicfoot. The foam density is a function of how much of the blowing agent orblowing agent mixture (i.e., the azeotrope-like mixture and anyauxiliary blowing agent, such as carbon dioxide, chemical blowing agentor other co-blowing agent) is present in the molten polymer. These foamsare generally rigid but can be made in various grades of softness tosuit the end use requirements. The foams can have a closed cellstructure, an open cell structure or a mixture of open and closed cells,with closed cell structures being preferred. These foams are used in avariety of well known applications, including but not limited to thermalinsulation, flotation, packaging, void filling, crafts and decorative,and shock absorption.

In other embodiments, the invention provides foamable compositions. Thefoamable compositions of the present invention generally include one ormore components capable of forming foam, such as polyurethane,polyisocyanurate, and phenolic-based compositions, and a blowing agentcomprising at least one azeotrope-like mixture described herein. Incertain embodiments, the foamable composition comprises thermoplasticmaterials, particularly thermoplastic polymers and/or resins. Examplesof thermoplastic foam components include polyolefins, such aspolystyrene (PS), polyethylene (PE), polypropylene (PP) andpolyethyleneterepthalate (PET), and foams formed therefrom, preferablylow-density foams. In certain embodiments, the thermoplastic foamablecomposition is an extrudable composition.

In certain embodiments, provided is a method for producing such foams.It will be appreciated by those skilled in the art, especially in viewof the disclosure contained herein, that the order and manner in whichthe blowing agent is formed and/or added to the foamable compositiondoes not generally affect the operability of the present invention. Forexample, in the case of extrudable foams, it is possible to mix inadvance the various components of the blowing agent. In certainembodiments, the components of the foamable composition are not mixed inadvance of introduction to the extrusion equipment or are not added tothe same location in the extrusion equipment. Thus, in certainembodiments it may be desired to introduce one or more components of theblowing agent at first location in the extruder, which is upstream ofthe place of addition of one or more other components of the blowingagent, with the expectation that the components will come together inthe extruder and/or operate more effectively in this manner. In certainother embodiments, two or more components of the blowing agent arecombined in advance and introduced together into the foamablecomposition, either directly or as part of premix which is then furtheradded to other parts of the foamable composition.

EXAMPLES

The invention is further illustrated in the following example which isintended to be illustrative, but not limiting in any manner. For therelevant examples, an ebulliometer of the general type described bySwietolslowski in his book “Ebulliometric Measurements” (Reinhold, 1945)was used.

Example 1

An ebulliometer consisting of vacuum jacketed tube with a condenser ontop which was further equipped with a Quartz Thermometer or a thermistorwas used. About 10 cc of trans-HFO-1233zd was charged to theebulliometer and then methanol was added in small, measured increments.Temperature depression was observed when methanol was added, indicatinga binary minimum boiling azeotrope had been formed. From greater than 0to about 51 weight percent methanol, the boiling point of thecomposition changes less than about 1.3° C. The boiling points of thebinary mixtures shown in Table 1 changed by less than about 0.02° C.Thus the compositions exhibited azeotrope and/or azeotrope-likeproperties over these ranges. To conform result two such ebulliometerswere set up side by side of which one contained pure solvent and theother one was set up with trans-HFO-1233zd and 2^(nd) component wasadded as mentioned before. The difference of temperatures in the two wasalso measured.

Example 2

An ebulliometer consisting of vacuum jacketed tube with a condenser ontop which was further equipped with a Quartz Thermometer or a thermistorwas used. About 35 g trans-HFO-1233zd is charged to the ebulliometer andthen n-pentane was added in small, measured increments. Temperaturedepression was observed when n-pentane was added to trans-HFO-1233zd,indicating a binary minimum boiling azeotrope had been formed. Fromgreater than 0 to about 30 weight percent n-pentane, the boiling pointof the composition changes less than about 0.8° C. The boiling points ofthe binary mixtures shown in Table 2 changed by less than about 0.02° C.Thus the compositions exhibited azeotrope and/or azeotrope-likeproperties over these ranges.

Example 3

An ebulliometer consisting of vacuum jacketed tube with a condenser ontop which was further equipped with a Quartz Thermometer or a thermistorwas used. About 17 g trans-HFO-1233zd is charged to the ebulliometer andthen isopentane was added in small, measured increments. Temperaturedepression was observed when isopentane was added to trans-HFO-1233zd,indicating a binary minimum boiling azeotrope had been formed. Fromgreater than about 0 to about 30 weight percent isopentane, the boilingpoint of the composition changed by about 0.8° C. or less. The boilingpoints of the binary mixtures shown in Table 3 changed by less thanabout 0.2° C. Thus the compositions exhibited azeotrope and/orazeotrope-like properties over these ranges.

Example 4

An ebulliometer consisting of vacuum jacketed tube with a condenser ontop which was further equipped with a Quartz Thermometer or a thermistorwas used. About 17 g neopentane is charged to the ebulliometer and thentrans-HFO-1233zd was added in small, measured increments. Temperaturedepression was observed when trans-HFO-1233zd was added to neopentaneindicating a binary minimum boiling azeotrope had been formed. As shownin Table 4, compositions comprising from about 19 to about 49 weightpercent trans-HFO-1233zd had a change in boiling point of 0.1° C. orless. Thus the compositions exhibited azeotrope and/or azeotrope-likeproperties over at least this range.

Example 5

An ebulliometer consisting of vacuum jacketed tube with a condenser ontop which was further equipped with a Quartz Thermometer or a thermistorwas used. About 18 g trans-HFO-1233 is charged to the ebulliometer andthen trans-1,2-DCE was added in small, measured increments. Temperaturedepression was observed when trans-1,2-DCE was added to trans-HFO-1233,indicating a binary minimum boiling azeotrope was formed. From greaterthan about 0.01 to about 53 weight percent trans-1,2-DCE, the boilingpoint of the composition changed by about 0.7° C. or less. The boilingpoints of the binary mixtures shown in Table 4 changed by less thanabout 0.3° C. Thus the compositions exhibited azeotrope and/orazeotrope-like properties over these ranges.

Anamount of cis-HFO-1233zd is charged to the ebulliometer and thenisohexane is added in small, measured increments. Temperature depressionis observed when isohexane is added to cis-HFO-1233, indicating a binaryminimum boiling azeotrope is formed. The compositions exhibit azeotropeand/or azeotrope-like properties over a range of about 70 to 99.5 weightpercent cis-1233zd and about 0.5 to about 30 weight percent isohexane.More pronounced azeotrope and/or azeotrope-like properties occur over arange of about 85 to 99.5 weight percent cis-1233zd and about 0.5 toabout 15 weight percent isohexane; and even more pronounced over a rangeof about 93 to 99.5 weight percent cis-1233zd and about 0.5 to about 7weight percent isohexane.

Example 31

An azeotrope-like mixture containing 98% by weight trans-HFO-1233zd withabout 2% by weight methanol is loaded into an aerosol can. An aerosolvalve is crimped into place and HFC-134a is added through the valve toachieve a pressure in the can of about 20 PSIG. The mixture is thensprayed onto surface demonstrating that the azeotropic mixture is usefulas an aerosol.

Examples 32-57

The steps of Example 31 are generally repeated for Examples 32-57,except that the azeotrope-like mixture identified in the Table below isused instead of trans-HFO-1233zd and methanol.
